Earlier this year, William Dalrymple of the The Paris Review interviewed Tibetan monk Tashi Passang:
Can one be both a monk and a resistance fighter?
Once you have been a monk, it is very difficult to kill a man. But sometimes it can be your duty to do so.
I knew that if I stayed in a monastery under the Chinese there was no point in being a monk. They wouldn’t let me practice my religion. So, to protect the ways of the Lord Buddha, the Buddhist dharma, I decided to fight.
Isn’t nonviolence an essential aspect of being a monk?
Yes, nonviolence is the essence of the dharma. This is especially true for a monk. The most important thing is to love each and every sentient being.
